While you’re tending to your fish in Happy Aquarium, be on the lookout for a new adoptable pet in the form of a baby seal.

You’ll be notified that you’ve found a baby seal in the same way you are all other adoptable pets, via an in-game pop-up. You’ll have the option to either ignore the lost seal (how cruel!) or help it find a home by posting your discovery to your wall in the form of a news item, that friends can click on to adopt the seal for themselves.

The appearance of these adoptable pets is random, so if you’re desperate to find one, your best bet is to leave the game window running in the background while you do other things.
